Batman Returns

(UNI) Password generator:
Some notes about the password system and the game itself:
1. Stage 6-1 doesn't generate any passwords normally during the game, because there is no fatal events on it, you just can't die there. But you still able to get to this stage with the custom generated password.
2. The "Damage taken" counter is what you've got every time you get a hit from enemy or die. Regular hits add 8 times of the hit power value to this counter, the game over add 1024 instantly. The amount of continues you may use is unlimited, but the more you die or get hits, the bigger the damage counter. There are two main effects depends on it:
 a) the amount of HP you got refilled after continue; calculated as 0x28+(damage/128), but not much than your current HP capacity
 b) the different endings; less damage counter, more detailed the ending
 There are total 4 ending variants. Two are the good ones, two are the bad.
  1. The damage counter above 14848: only the staff roll with the stage 1-2 boss easter and the final message "YOU TOOK TOO MUCH TIME TO GET HERE. TRY GETTING HERE SOONER."
  2. The damage counter between 14848 and 9984: additional bat signal screen before the staff, the same stage 1-2 easter and the message "YOUR SKILL HAS IMPROVED, BUT YOU'RE NOT A REAL HERO YET."
  3. The damage counter between 9984 and 5376: the full demo sequence with the scene of the Penguin death, following the bat signal and staff roll with stage 2-3 boss Catwoman easter instead, and the message is "CONGRATULATIONS! BATMAN,YOU'VE SAVED GOTHAM CITY."
  4. The damage counter less than 5376: additionally a Catwoman picture appears on the bat signal screen, and the final message is "AWESOME! YOU ARE THE HERO OF ALL HEROES."
3. The "Game start" flag is used to determine if you access the password menu after the game over screen or you just powered up the console. Depends on it will or not clear some game variables. This prevents the game parameters and flags from erasing between game plays, and even if you choose "END" at the game overs screen, you can always go to the password menu and enter the default generated passwords (which is the same as on the game over screen) and continue the game. However, this flag is set to 1 ALWAYS when you start a new game or continue one way or another, it's is only has value 0 before the first game play after the reset. So technically, every password generated by the game after the game is started has this flag set, and only 4 random default passwords generated after the game reset, has this flag clear. When you generate any valid password, doesn't matter if you set this bit or not.
4. The "Test tube" flag is a special item, not displayed on HUD, but you can obtain it on stage 2-2 inside the cat's eye on the background after beating two trident armed enemies. Used automatically on the stage 2-3 boss Catwoman, cuts its HP by half.
5. The "Conversation" flag is set when you record the Penguins conversation in one of the rooms of the stage 3-1. This will change the level layout and allows you to complete it. You can't avoid setting this flag during the normal game, generated passwords with this flag set lead to the second part of the stage.
6. Also there is a special anti-pirate flag, if set, it makes any valid passwords not working. Here this flag is forced to be disabled for obvious reason.
7. There are two special debug flags, that can't be set during the game, and may be only generated. The invulnerability flag disables the HP decreasing. The Level Select flag is another debug leftover, allows you any time during the game, except the cutscenes, change current stage up to stage 4-2 instantly by pressing Left or Right on controller 2. The stages above 4-2 can't be accessed with this cheat.
8. "Box in hand" and "Box filled" are represents the special HP storage item. First is for amount of this items in your posession (given to you instantly after the stage 1-2 boss, the rest are hidden at some places). The second is amount of filled ones with HP. Actual HP counter in this game is 8-bit in size, so can contain as much as 255 HP. Only 64 HP is displayed in the HP bar on HUD, this takes only 6 lower bits of the number. When calculating your HP, the game will check for amount of boxes in posession and fills the higher two bits of the HP depending on it. So normally during the game you can't get the HP counter more than 64+(box*64) value. However, game doesn't check this when you lose your HP and decreasing it as if it full 8-bit value, so with this password generator, you can set "Hitpoints" + "Box filled" vealues to maximum to get 255 HP ingame without posessing the boxes at all. Unfortunately, the HP will be dropped back to 64 after the first continue.
9. And finally, there are two unused bits in passwords, that can be used for unique passwords generation, but doesn't appears to have any effects during the game.

Captain Tsubasa Vol. II - Super Striker

(UNI) Password generator:
Some notes:
1. There are 34 valid rounds in this game, but the password system allows up to 64 rounds, so all rounds between 35 and 66 will obviously glitch the game or hang it. You can try it by setting the corresponding checkbox.
2. The Jun Misugi's guts test starts from round 17. If its guts drops under 100 after the round is over (no matter if you win or loose) then in the next round it will have zero guts. This behaviour can be stored in the password as well.
3. There are much more characters in this game in 3 different teams than the password system can store. So, one player position in the password used to store level for a multiple characters, for three teams at once. Here is the table with the lists of characters in all teams for every player slot in password.

Godzilla - Monster of Monsters!, Godzilla

(UNI) Password generator:
Note, there are a lot of redundancy in this password system. Most of parameters can be invalid (valid stages are from 0 to 7, valid locations not higher than 64, etc...), there are two unused Monsters slots for unused player characters (see tcrf.net). It is possible to generate malformed password without valid structure with almost any data inside, so passwords like "GH1D0RA" are possble (can be generated using the "Hack" option).

Keroppi to Keroriinu no Splash Bomb!

(UNI) Password generator:
Note, the password system allows to store some parameters which cannot be generated by the game (radius can't be higher than 3). This leads to the glitch passowrds, which doesn't allow the correct password generation further during the game if used.
Also note: the password system has a bug causing the game can't generate the passwords with symbols "゛゜", this bug has a workaround in the code, so such passwords cannot be generated at all. Still, you can use these symbols when generating the password and they will be decoded correctly. This also can be allowed with the "Glitch pass" checkbox.
